  "body": "J. M. Gelbord (PSU) reports on behalf of the Swift Team:\n\nAt 21:03:29 UT BAT triggered on a source near the Galactic center  \n(trigger # 431582).  The slew was delayed by 51.8 minutes due to the  \nEarth limb observing constraint.\n\nAt the time of the BAT trigger, the source was identified by both the  \non-board BAT catalog and the GCN ground catalog as IGR J17475-2822.   \nHowever, preliminary analysis of the XRT data taken an hour after the  \ntrigger reveals two other point sources within an 8 x 8 arcmin region  \ncentered on the BAT position.  These sources are consistent with the  \npositions of IGR J17464-2811 and 1RXS J174704.6-280843.  These sources  \nare 0.8 and 3.5 arcmin from the BAT position, respectively, with IGR  \nJ17464-2811 the brighter source by about a factor of 6.\n\nWe consider IGR J17464-2811 to be the likely counterpart of the BAT  \ntrigger.  This source is not in either the on-board BAT catalog or the  \nGCN ground catalog. If it had been, it would have been the counterpart  \nidentified at the time of the trigger and not IGR J17475-2822.",
